Title: Optical reproducing device
Inventor: KANEHIRA ATSUSHI
IPC: G11B7/005
Filed: 1990-09-25
Abstract: PURPOSE:To improve the detecting resolution and to reduce detecting errors as well and then to achieve high recording density by making the width of each element of a linear array positioned in a place where a higher-order diffraction peak corresponding to a space between pits appears an optimum size. CONSTITUTION:A laser beam of a laser diode 12 is projected to plural pits 24 formed at an interval corresponding to information on an optical disk 22 via a collimator lens 14, a polarization beam splitter 16, a 1/4- lambda plate 18 and an objective lens 20. It is preferable that the size of this pit is an extent of a wavelength of the reproducing laser diode 12, and the pit interval is changed to an extent of 2-6 times of the wavelength. The beam is reflected by its irradiated surface and also diffracted by a set of pits to irradiate a photodiode array 26 via the objective lens 20, the 1/4-lambda plate 18 and polarization beam splitter 16. Now, since the element width of the photodiode array is changed in accordance with a diffraction pattern, the number of resolution points is increased as compared with a case of using a linear array having the same element width, and the recording density is improved.

Title: Data recording medium
Inventor: SHIMATANI TAKESHI
IPC: B42D15/10
Filed: 1990-09-25
Abstract: PURPOSE:To effectively prevent forgery and alteration by providing a colored layer absorbing infrared rays on a substrate and providing a discharge recording layer making the colored layer invisible and reflecting infrared rays thereon and further providing a concealing layer permitting infrared rays to transmit and making the discharge recording layer invisible thereon. CONSTITUTION:A colored layer 2 absorbing infrared rays is provided to the surface of a card substrate 1 and a discharge recording layer 3 making the colored layer invisible and electrically recording discharge breakdown recording data 4 is provided on the colored layer 2 and a conductive concealing layer 5 making the discharge recording layer 3 invisible is provided on the discharge recording layer 3. Data is recorded on the discharge recording layer 3 of the prepaid card thus constituted by a discharge head. A pattern part is subjected to discharge breakdown to expose the colored layer but, since the colored layer is concealed by the concealing layer 5, the presence thereof can not be visually confirmed from the outside. Next, when the pattern part is read, the card is irradiated with infrared rays and the pattern part does not almost reflect infrared rays but the unbroken part shows high reflectivity. Therefore, the genuinness of the card can be discriminated or data such as amount can be confirmed from the difference in reflectivity.

Abstract: PURPOSE:To allow the radiography of the left and right coronary arteries and the left ventricle from the upper arm by using the catheter which has a catheter body of a specific outside diameter, is substantially straight in the specific length from the front end and is curved in this straight fornt end part at a specific angle with the axial direction of the catheter body. CONSTITUTION:The outside diameter of the catheter 1 is confined to <=2.1mm and, therefore, the catheter can be introduced into the vein of the upper arm by using a sheath, by which the patient's burden is decreased and the exchange of the catheter and guide wire is facilitated. The catheter body 2 is formed substantially straight in the length L of 10 to 45mm from the front end part 3 thereof in the state of not exerting external force thereto. This front end part 3 is curved at 45 to 70 deg. angle in the axial direction of the catheter body 2. The radiography of the vein graft, which is frequency executed in addition to the left and right coronary radiography and the left ventricle radiography, is hardly executable and the catheter is liable to enter the left ventricle at the time of inserting the catheter into the coronary arterie hole if the angle is smaller than 45 deg. in this case. The insertion of the catheter into the right coronary artery is difficult if the angle is larger than 70 deg..

Title: Protector for compressor
Inventor: KURITA YASUHIRO
IPC: F04B49/10
Filed: 1988-10-14
Abstract: PURPOSE:To keep off any damage to a compressor due to nonconformity in a refrigerating cycle by installing a pressure switch, detecting refrigerant pressure in the compressor, in conjunction with an electromagnetic sensor part which generates a pulse signal in a detected element with rotation of a drive circuit of the compressor and detects its rotational frequency. CONSTITUTION:A detector 1 of a protector for a compressor is provided with a movable rotation detector 2 held by an elastic bellows 3. This rotation detector 2 has a permanent magnet 201, a rotation detecting coil 203 and an iron core 204, and a movable pin 4 is set up in the center. A reversing plate 6 at the bellows side and a low pressure detecting spring 5 at the opposite side press a movable piece 502. The detector 1 is adjacently attached to a high pressure chamber of the compressor, detecting a detected element of a compressor shaft and generating a pulse. On the other hand, a switch of an electromagnetic clutch comes to OFF by pushing force at time of nonpressure in the high pressure chamber and to ON by pushing force of the bellows 3 at time of normal pressure respectively. At time of abnormally high pressure, the reversing plate 6 pushes the pin 4 upward and the switch is turned off. Thus, the compressor is protected from this abnormally high pressure in a refrigerating cycle and a gas non-sealing state.
